Reporting on files that are not touched at all by tests

[abelnation]

Currently if my tests don't touch a src file at all, the file is omitted from the report. Is there a way to report on all src files regardless? Here is my config:

    {
        instrument: {
            files: '<%= jshint.src.src %>',
            options: {
                // lazy: true,
                basePath: '<%= paths.coverage %>/src_inst/',
            }
        },

        reloadTasks: {
            rootPath: '<%= paths.coverage %>/instrument/tasks'
        },

        storeCoverage: {
            options: {
                dir: reportDir,
            }
        },

        makeReport: {
            src: '<%= paths.coverage %>/reports/**/*.json',
            options: {
                type: ['lcov', 'html'],
                dir: reportDir,
                print: 'detail'
            }
        }
    }
